What is a Fetal Growth Scan?
A fetal growth scan is a special ultrasound test. Doctors use it to check your baby’s size and growth during pregnancy. This scan helps monitor fetal development and makes sure your baby is growing well. Usually, doctors use a safe and painless ultrasound machine. The scan creates pictures of your baby inside the womb. Because it is non-invasive, there is no risk to you or your baby.
Why is a Fetal Growth Scan Important?
Often, a fetal growth scan gives important information about your baby’s health. For example, it can show if your baby is smaller or larger than expected. Sometimes, babies grow slower or faster than normal. Early detection helps doctors plan the best care. In addition, this scan can spot problems with the placenta or amniotic fluid. Both are important for your baby’s growth. According to the World Health Organization, regular scans help lower the risk of birth problems.
When is a Fetal Growth Scan Performed?
Doctors usually recommend a fetal growth scan between 28 and 32 weeks of pregnancy. However, some women may need it earlier or later. For instance, if your doctor thinks your baby is not growing as expected, you may get extra scans. Also, women with certain health conditions, like high blood pressure or diabetes, may need more scans. In some cases, your doctor may suggest a scan if you had problems in a past pregnancy. Every pregnancy is unique, so your doctor will decide the best time.
How is a Fetal Growth Scan Done?
During a fetal growth scan, you will lie on an exam table. First, a gel is placed on your belly. Then, the technician moves a small device called a transducer over your skin. This device sends sound waves into your body. The waves bounce back and create images of your baby on a screen. The scan usually takes about 20 to 30 minutes. Because the process is gentle, you should not feel pain. Most clinics, including those in your area, use the latest ultrasound for fetal growth technology.
What to Expect During the Scan
Before the scan, you may be asked to drink water. This helps make the images clearer. During the scan, you can see your baby on the screen. Sometimes, the technician will point out your baby’s head, arms, and legs. After the scan, you can clean off the gel. Usually, you can return to your normal activities right away. If you have questions, the staff will explain what they are doing. Many parents find this scan exciting because they get to see their baby’s growth during pregnancy.
Understanding the Results
After your fetal growth scan, your doctor will review the images. They will measure your baby’s head, belly, and legs. These measurements help estimate your baby’s weight and growth rate. If your baby is growing well, you may not need more scans. However, if the scan shows slow or fast growth, your doctor may suggest more tests. Sometimes, changes in growth can mean a problem with the placenta or amniotic fluid. Your doctor will explain what the results mean and what steps to take next.
Factors Affecting Fetal Growth
Many things can affect your baby’s growth during pregnancy. For example, your health and nutrition play a big role. Some other factors include:
Because these factors can change how your baby grows, your doctor may monitor you more closely. Eating healthy foods, avoiding smoking, and attending all check-ups can help support your baby’s growth.
